Have you browsed the LDAP entries in ActiveDirectory to see if they match similar entries for working windows hosts. Under the computer entry, look carefully at dnsHostname and servicePrincipalName. For a server, there are many many entries for these two variables. CIFS/x2, HOSTx2, LDAPS?/, ..... and so on.

CentOS 5.3 getent does not return data from the active directory (ads)
I have installed and configured kerberos and samba so that the server can be a member of an existing Active Directory (AD). Correct configuration of kerbos was verified using kinit and klist. The samba configuration was verified by using "smbclient -k -L server". winbind was verified by using "wbinfo -g". The problem seems to be nsswitch accessing winbindd to get group information via the "getent group" command. I added winbind to the /etc/nsswitch.conf file like so:
[root@nagios ~]# grep winbind /etc/nsswitch.conf passwd: files winbind shadow: files winbind group: files winbind
I verified that all dynamic libraries are being accessed correctly by using "strace getent group".
Below is the debug output of winbindd when issuing various commands that interact with it. The commands are noted in (parenthesis).
